Description

Technical field: [0001] The invention belongs to the technical field of coatings, and particularly relates to a durable and efficient nanometer antibacterial waterborne wood coating. Background technique: [0002] With the rapid development of industry and the deteriorating environment, coatings are developing in the direction of functionalization and ecologicalization. The development of functional coatings that meet environmental protection requirements has become the consensus of the industry. Wood coatings account for more than 10% of the world's total coating consumption. In the field of wood coatings, furniture plays an important role in people's working and living environments, but it may also become a medium for the spread of germs. In recent years, the harm of various bacteria and viruses has obviously increased. According to the microbiological test of daily office desks by Fudan University School of Medicine, the harmful bacteria Hanlang is 4 times that of ordinary bat...
